{"id":"CVE-2023-52083","aliases":["GHSA-4wvw-75qh-fqjp"],"url":"https://o3.security/vulnerability/CVE-2023-52083","summary":"Stored XSS through privileged upload of Media Manager file followed by renaming","details":"Winter is a free, open-source content management system.  Prior to 1.2.4, users with the `media.manage_media` permission can upload files to the Media Manager and rename them after uploading. Previously, media manager files were only sanitized on upload, not on renaming, which could have allowed a stored XSS attack. This issue has been patched in v1.2.4.","published":"2023-12-28T22:11:55.494Z","modified":"2026-08-12T03:51:43.878032292Z","cvss":{"score":2,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:N"},"epss":{"score":0.00311,"percentile":0.23945,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"winter/wn-system-module","fixedVersion":"1.2.4"}],"fix":{"url":"https://github.com/wintercms/winter/commit/2969daeea8dee64d292dbaa3778ea251e2a7e491","label":"wintercms/winter@2969dae"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52083.json"},{"type":"ADVISORY","url":"https://github.com/wintercms/winter/security/advisories/GHSA-4wvw-75qh-fqjp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52083"},{"type":"FIX","url":"https://github.com/wintercms/winter/commit/2969daeea8dee64d292dbaa3778ea251e2a7e491"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:43.878032292Z"}}
